Can light-independent be accepted? I tried some real creative ways of spelling that one but didn't think of adding "reaction"

-SAN or SA node should be acceptable - Nitrogenous bases or DNA bases should be accepted - base pairs as an answer is incorrect. -Calvin cycle, Calvin-Benson cycle or carbon fixing are also acceptable answers for light independent reactions. - Neurone is spelled neuron. - Acetyl CoA is also an acceptable answer.
